Our theme is compatible with “WP Super Cache plugin, W3 Total Cache plugin” You are using a third-party cache plugin that is not included in our compatible plugins list nor we officially tested it with our theme. So try to avoid using this plugin and if necessary then use the cache plugins I told you about.
Note: Before using any cache plugins first please contact your service provider to flush the server completely then proceed to install the cache plugin and use it.
